  • Chromium nitride is very incompressible, making it ideal for industrial coatings. However, it is now shown that the material softens at high pressure and low temperature in connection with a phase transition from cubic to orthorhombic structure. The results could be fundamental in designing ways to improve the mechanical properties of superhard CrN.

  • External perturbations can induce 3D charge order in cuprates, but the 3D correlation length is limited and the mechanism is not well understood. Ruiz et al. show that Pr substitution in YBa2Cu3O7 enhances interplanar orbital coupling and stabilizes coherent 3D charge order that coexists with superconductivity.
